Not so Shore Anymore: The New Imperatives When Sourcing in the Age of Open

Software outsourcing has been the subject of much research in the past 25 years, largely because of potential cost savings envisaged through lower labour costs, ‘follow-the-sun’ development, access to skilled developers, and proximity to new markets. In recent years, the success of the open source phe-nomenon has inspired a number of new forms of sourcing that combine the potential of global sourcing with the elusive and much sought-after possibility of increased innovation. Three of these new forms of sourcing are opensourcing, innersourcing and crowdsourcing. Based on a comparative analysis of a number of case studies of these forms of sourcing, we illustrate how they differ in both significant and subtle ways from outsourcing. We conclude that these emerging sourcing approaches call for conceptual development and refocusing. Specifically, to understand software sourcing in the age of open, the important concept is no longer ‘shoring,’ but rather five identified imperatives (governance sharedness, unknownness, intrinsicness, innovativeness and co-opetitiveness) and their implications for the development situation at hand

Criminaliteit en criminologie in een gedigitaliseerde wereld

__Abstract__ Wat betekent de komst van het internet voor criminaliteit en de bestrijding ervan? Dit themanummer staat stil bij deze belangrijke ontwikkeling in onze samenleving. In deze redactionele inleiding staan we allereerst stil bij de aan het internet gelieerde criminaliteit: cybercrime. Wat is het precies? Vervolgens richten we ons op de criminologische hoofdvragen die de opkomst van het internet met zich meebrengt. Ontstaat hierdoor meer criminaliteit? Wie zijn de betrokkenen? Wat doen we ertegen? Verder staan we stil bij de mogelijkheden voor het doen van criminologisch onderzoek met onlinemateriaal, zoals onlineobservatie en Big Data. Tot slot geven we een schets van de manier waarop hoogwaardige ICT behulpzaam kan zijn in de opsporing van criminaliteit. Al met al kunnen we spreken van een jong aandachtsveld binnen de criminologie waar tal van interessante onderzoeksthema’s vragen om een verdere uitwerking

Wine of Cool-climate Areas in South Poland

A number of new vinery production regions, especially in the southern parts of Poland, have appearedin the last ten-odd years. This study was aimed at completing the chemical characterisation of wineproduced from ten Polish grape cultivars planted near Krakow. The wine was analysed to determineorganic acid concentrations, total polyphenols and extract content, antioxidant activity, alcohol content,total acidity and pH. Moreover, a sensory analysis was performed on the wine. Significant differenceswere recorded between red and white wine. The total acidity expressed as tartaric acid, and tartaric andmalic acid concentrations, were significantly higher in white and red wines, whereas antioxidant activityand phenolic content were significantly higher in the red wines. Similarities and relationships betweenvarious parameters and specific wine brands were further examined with cluster analysis. Our resultsshow that, under Polish climatic conditions, it is possible to produce wine with quality comparable towine from established wine denomination regions. Selected wine brands showed high antioxidantactivity (FRAP – ferric reducing antioxidant power) and a high level of polyphenols. This study alsoprovides confirmation that wines from colder climates frequently reveal unique and desirable properties

Not so shore anymore: the new imperatives when sourcing in the age of open

Software outsourcing has been the subject of much research in the past 25 years, largely because of potential cost savings envisaged through lower labour costs, ‘follow-the-sun’ development, access to skilled developers, and proximity to new markets. In recent years, the success of the open source phe-nomenon has inspired a number of new forms of sourcing that combine the potential of global sourcing with the elusive and much sought-after possibility of increased innovation. Three of these new forms of sourcing are opensourcing, innersourcing and crowdsourcing. Based on a comparative analysis of a number of case studies of these forms of sourcing, we illustrate how they differ in both significant and subtle ways from outsourcing.

The Pneumococcal Serine-Rich Repeat Protein Is an Intra-Species Bacterial Adhesin That Promotes Bacterial Aggregation In Vivo and in Biofilms

The Pneumococcal serine-rich repeat protein (PsrP) is a pathogenicity island encoded adhesin that has been positively correlated with the ability of Streptococcus pneumoniae to cause invasive disease. Previous studies have shown that PsrP mediates bacterial attachment to Keratin 10 (K10) on the surface of lung cells through amino acids 273-341 located in the Basic Region (BR) domain. In this study we determined that the BR domain of PsrP also mediates an intra-species interaction that promotes the formation of large bacterial aggregates in the nasopharynx and lungs of infected mice as well as in continuous flow-through models of mature biofilms. Using numerous methods, including complementation of mutants with BR domain deficient constructs, fluorescent microscopy with Cy3-labeled recombinant (r) BR, Far Western blotting of bacterial lysates, co-immunoprecipitation with rBR, and growth of biofilms in the presence of antibodies and competitive peptides, we determined that the BR domain, in particular amino acids 122-166 of PsrP, promoted bacterial aggregation and that antibodies against the BR domain were neutralizing. Using similar methodologies, we also determined that SraP and GspB, the Serine-rich repeat proteins (SRRPs) of Staphylococcus aureus and Streptococcus gordonii, respectively, also promoted bacterial aggregation and that their Non-repeat domains bound to their respective SRRPs. This is the first report to show the presence of biofilm-like structures in the lungs of animals infected with S. pneumoniae and show that SRRPs have dual roles as host and bacterial adhesins. These studies suggest that recombinant Non-repeat domains of SRRPs (i.e. BR for S. pneumoniae) may be useful as vaccine antigens to protect against Gram-positive bacteria that cause infection

In search of the origins and enduring impact of agile software development

The Agile Manifesto is a philosophical touchpoint for all agile software development (ASD) methods. We examine the manifesto and some of its associated agile methods in an effort to identify the major impacts of ASD. We have encountered some difficulty in delineating agile and non-agile software processes, which is partially the result of terminological confusion. It is clear from the volume of published research that ASD has made a significant contribution, and we have identified two lasting and important impacts. Firstly, the reduction in iteration durations and secondly, the push for reduced levels of documentation (especially in relation to software requirements). Other aspects of the Agile Manifesto may not have exerted a significant impact; for example, the use of tooling to automate processes has become central to continuous software engineering (CSE) and may not be wholly congruent with the manifesto. Furthermore, many organisations may still rely on business contracts despite calls in the manifesto for greater levels of informal customer collaboration

Biomass and floristic patterns in the ground layer vegetation of box-gum grassy eucalypt woodland in Goorooyarroo and Mulligans Flat Nature Reserves, Australian Capital Territory

We establish a methodology and present baseline data for a long-term grassy woodland restoration study that commenced in 2007 in two nature reserves (Mulligans Flat, Goorooyarroo (35° 9–13’ S; 149° 9–12’ E)) totalling 1386 ha on the northern boundary of Canberra, in the Australian Capital Territory in south eastern Australia. The experimental infrastructure comprises 96 × 1 ha sites established in Eucalyptus blakelyi / Eucalyptus melliodora dominated woodland. These are being subjected to varying kangaroo grazing pressure and augmentation with logs, while burning treatments are planned. One reserve (Mulligans Flat) has been fenced for feral predator control and contains half the sites, forming a companion experiment to Goorooyarroo. Our baseline floristic study comprised estimates, at the site level, of ground layer biomass, species biomass, ground cover types and soil (0–10 cm) properties. From these data we conclude that the groundlayer vegetation is dominated by Joycea pallida, Austrodanthonia spp., Themeda australis and Aristida ramosa. These grasses varied in abundance according to differences in soil pH, phosphorus and to a lesser extent nitrates. Forb frequencies were highly sensitive to nitrate levels with annual exotic forbs dominating at high nitrate sites. More generally, soil nutrient levels and exotic species in some sites indicated areas of previous pasture improvement activities. Biomass estimates indicated extremely high grazing pressure, sufficient to negatively affect the habitat quality for ground-dependent fauna and some soil processes. These data will provide an important basis for examining rates of ecosystem recovery under different restoration strategies

An Empirical Study of Bots in Software Development -- Characteristics and Challenges from a Practitioner's Perspective

Software engineering bots - automated tools that handle tedious tasks - are increasingly used by industrial and open source projects to improve developer productivity. Current research in this area is held back by a lack of consensus of what software engineering bots (DevBots) actually are, what characteristics distinguish them from other tools, and what benefits and challenges are associated with DevBot usage. In this paper we report on a mixed-method empirical study of DevBot usage in industrial practice. We report on findings from interviewing 21 and surveying a total of 111 developers. We identify three different personas among DevBot users (focusing on autonomy, chat interfaces, and "smartness"), each with different definitions of what a DevBot is, why developers use them, and what they struggle with. We conclude that future DevBot research should situate their work within our framework, to clearly identify what type of bot the work targets, and what advantages practitioners can expect. Further, we find that there currently is a lack of general purpose "smart" bots that go beyond simple automation tools or chat interfaces. This is problematic, as we have seen that such bots, if available, can have a transformative effect on the projects that use them.Comment: To be published at the ACM Joint European Software Engineering Conference and Symposium on the Foundations of Software Engineering (ESEC/FSE
